Be it known that-I, Axnn ject of the King of Denmark, residing at 101 Flushing avenue, Astoria, Long Island, in the countyof Queens and State of New York, have invented new and useful 'Improveme'nts in Antiskid Devices, of which the following is a specification.

This invention relates to antiskid devices for motor vehicles, the broad object ,in view being to "provide in connection, with thewheel or chassis of a motor vehicle. one; (or more rotary motor driven antiskid mom-j bergeach of which is preferably of cylindrical formation and arranged torotate on an axis at right angles to the vehicle axis. I A further objector the invention is to e vicle in connection with said antiskid mem her or members, means for positively dijiving said memberor' members so as to cause it or them when in contact with tlielground chine, the supporting or controlli for said member or men'ibers being as they approach the outer interrupt any skidding action be sardivi'rh object of the invention is; to; pv

theyimay befelevatedc'lear of the road sur- 'hati'geor. al-lowecl' to ino've downwardly into v eingaging contactwithth'e road surface.

With the above and other objects'in View,

t heinvention consists-in the novel conustruc "tion, combination a d herein described, illustrated and claimed. In the accompanying dra'w1ngs to show the invention in its applied relation l thereto.

Fig. 2 is a rear elevation of thesame showing the antiskid members elevated.

- FigB-is' a similar'view showing the antiskid members depressed. 1

qFigA-is a fragmentary vertlcal longi tudinal section through the'vehicle. Fig. 5 is-a fragmentary side view of one of the antiskid members, illustrating the manner offn'ounting and operating thesame.

In the lrei erred embodiment of this in-- -vention,-t le' antiskid devices are arranged beneath the rear axle housing, the latter being shown at 1, 2 designating the housing arran ement of arts a 3 Figure 1 is a plan view of a srdiiciei'it pertion'of a motor. vehicle eha'ssls or wheelbase 1 for. thediflerential gearing, 3 the rear driv- BRASEN, a sub-'- ing wheels of the vehicle and 4 the vehicle frame.

Incarrying out the present invention ll.

the preferred embodiment thereof, I use two antiskid members 5 each preferablyin the form of a cylindrical body havingthe ends thereof tapered as indicated at 6; Each of the members 5 as will hereinafter appear, constitutes.means for elevating the rear portionof the veliiclc and also a traction roller,

the same being positively driven in a direction which will cause the same, upon coming in. contact with the road surface, to roll tof'ward the adjacent driving wheel Each of the antiskid members or rollers 5 has a shaft 7 which is mounted in the-arms 8 of a pivotedhanger, the hanger also comprising a support or clamp 9 .whichembraces the rear axle housing 1 and-is securely fastened in fixed relation thereto.

The meansfor driving the rollers or antiskid members 5 simultaneouslyvin opposite directions, comprises a gear 19 on the drive shaft 20 of the motor vehicle, the gear 19 being normally loose on said shaft but be- The arms 8 are connected to the clamping member 9- of the hanger by pivots 10 thus sis lowering the antlsklddmgj-w members? Q nnultaheeiisly,

i'n'g adapted to be thrown into engagement 'herewith by means of a clutch 21 slid-able on the shaft 20 and manually operable by .means of a' pedal 22 connected to a bell crank lever 23 supported beneath the floor 1240f the vehicle by means of a bracket 25,

the-lever 23 being connected by a ,rod to a clutch shifting fork or lever 27 which engages the clutch 21 as shown in Fig. 1. The. gear 19 meshes with another gear 28 of equal size and arranged at one side thereof. The hubs of the gears 19 and 28 are provided with sprocket wheels 29 from which chains 30 extend'laterally of the vehicle in opposite directions around larger sprocket wheels 31 on the pivot shafts upon which the hanger arms 8 are mounted preferably of cylindrical formation, revolve on axes at ri ht angles to the axes of the driving whee s; also that said rollers are 7 simultaneously driven in opposite directions so that when they are in contact with the road surface, they will roll toward thegdriving wheels 3, the hangers carrying said rollers being of such dimensions'that as the rollers approach the final limit of their movements toward the driving Wl eels of the vehicle, they .will press hard upon the road surface and slightly lift the vehicle driving wheels. The means for driving said antiskid rollers, may be thrown into operation instantly and as quickly thrown out of open ation so as not to result in any injury either to the antiskid rollers or the engine or to anyof the driving connection. After the skidding movement of the vehicle has been arrested, the antiskid members may be mestored to their elevated position as indicated in Fig. 2 where they may be held until again ,needed. The apparatus hereinabove described may be also conveniently used in a garage or other place for jacking up the driving wheels of the machine for any of the various purposes such as changing tires or placing the vehicle in temporary or dead storage, thereby relieving the Weight on the tires when the vehicle is not in use. It will of course be apparent also that the mechanism hereinabove described may be duplicated in connection with the front axle of the vehicle should it be deemed expedient or desirable for any reason.

I clainr:

2. In combination with a motor vehicle, two oppositely rotatable motor driven antiskid rollers having their axes at right angles t5 the axes of the vehicle Wheels and having cylindrical groundeengaging surfaces, and means for raising and depressing said rollers.
